摘要通过从暴露于铀裂变碎片的云母表面层中裂开而去除的薄片，已在电子显微镜中进行了透射检查。小于300埃的裂变碎片径迹。直径大于4微米，长度大于4微米的中子束，叠加在由相关中子轰击引入的一般背景上。轨道的性质进行了讨论。该技术可用于研究辐射引起的原子位移，以及粒子本身的性质和行为，其分辨率比以前更高。
Abstract Thin sheets, removed by cleavage from the surface layers of mica exposed to fission fragments from uranium, have been examined in transmission in the electron microscope. Fission fragment tracks which are less than 300 A. in diameter and greater than four microns in length have been seen, superimposed upon a general background introduced by associated neutron bombardment. The nature of the tracks is discussed. The technique can be used to study radiation indueed atomic displacements, and the nature and behaviour of the particles themselves, with higher resolution than has previously been possible.
